Sell 12 inch Continuous-slot Johnson Screens

详情

The V-shape  section plane of HuaDong Johnson well screen can avoid blockage, and make sure of the unimpeded water. Further more, the consecutive slot have more open area, and it can reduce the speed of the water entering to aviod the sand entering the screen under the great pressure, so Johnson well screens can filter sand better.

Continuous-slot Johnson well screens provide more intake area per unit area of screen surface than any other type. For any given slot size, this type of screen has maximum open area.

Main Advantage:

1. Production process continuity: V-shaped profile wires creating slots which enlarge inwardly and therefore avoid clogging and minimize downtime.

2. Low maintenance costs: Separation at the screen surface which can easily cleaned by scraping or back washing.

3. Maximum process output: Precise and continuous slot openings resulting in accurate separation without loss off media.

4. Low operational costs: Large open area with an effective flow, high yield and a low pressure drop (dP)

5. Long live: Welded at each intersection creating a strong and durable screen.

6. Reduced installation costs: supporting constructions eliminating costly support media and enabling a maximum flexibility in the design of components.

7. Chemical and thermal resistant: A variety of corrosion resistant stainless steel materials and many exotic alloys suitable for high temperatures and pressures.
